This product is a calibration loop from the manufacturer Chauvin Arnoux, specifically designed for checking and adjusting earth testing clamps. The loop serves as a reference device to precisely validate the display of measurement values on earth testing clamps. It is compatible with models C.A 6416, C.A 6417, and C.A 6418, which are used in the field of electrical safety and earthing measurements. The calibration loop enables immediate on-site verification of the measurement value display without requiring the devices to be sent to the factory.

Applications

The calibration loop is used in specialist trades and electrical installations, where the reliability of earthing measurement devices is critical. It serves for quality control and maintenance of earth testing clamps, particularly in testing protective conductors, earthing systems, and electrical installations. The application takes place on-site, for example during building maintenance, industrial plant servicing, or testing electrical installations according to VDE or DIN standards.

Functions and Equipment in Detail

The loop features 5 fixed resistance values serving as calibration references. These values enable precise verification of the measurement accuracy of earth testing clamps. If the display deviates from the reference values, adjustment can be performed directly on-site. Thus, the loop is a tool for device maintenance and validation without requiring return to the manufacturer.

Technology Explained Simply

The calibration loop simulates known resistance values that are measured by the earth testing clamp. The device’s display is compared with the predefined values to detect deviations. The fixed resistance values are selected to cover typical measurement ranges of earth testing clamps. The loop is mechanically robust and designed for use in the trade, requiring no additional power sources or external devices.

Compatibility and Accessories

The loop is specifically developed for earth testing clamps of models C.A 6416, C.A 6417, and C.A 6418. It is used directly on the device without additional adapters or converters. No further accessories are required to operate the loop.

Mounting and Installation

The calibration loop is simply inserted into the measuring loop of the earth testing clamp. Testing is performed by clamping the clamp around the loop and reading the measurement value. Adjustment is carried out using the control elements of the earth testing clamp, with the loop serving as the reference. No tools or additional steps are required.

Advantages in Operation

Immediate on-site verification reduces downtime and avoids the need to send devices to the factory. The fixed resistance values provide a reliable, reproducible reference. The loop is compact and easy to transport, making it particularly suitable for mobile applications in the electrical trade. Maintenance requires no special tools or additional equipment, increasing efficiency.
